Saliva-based colorimetric test as an index of gingival inflammation in epidemiologic studies
Community Dentistry and Oral Epidemiology
Colorimetric test may be a valid, reliable means of detecting major differences in the prevalence of gingival inflammation in most adult populations, although having little, if any, useful application among children at the mixed dentition stage.
Screening for periodontitis in pregnant women with salivary enzymes
Journal of Obstetrics and Gynaecology Research
Combining LDH, ALP, and occult blood showed the highest diagnostic performance, with a sensitivity value of 0.90, specificity value of 0.62, positive predictive value of 0.18, and negative predictive value of 0.98.
Effectiveness of the salivary occult blood test as a screening method for periodontal status
Journal of Periodontology
The sensitivity and specificity of the salivary occult blood test in screening for poor periodontal status were 0.72 and 0.52, respectively. In a multivariate logistic regression analysis, the results were significantly associated with the proportion of teeth with BOP and the proportion of teeth with PD ≥ 4 mm, independent of age, sex, use of antihypertensive medication, use of antidiabetic medication or insulin therapy, and the number of decayed or filled teeth.
Periodontal disease and related factors among Vietnamese dental patients
Oral Health & Preventive Dentistry
The perioscreen test showed moderate sensitivity (0.752) and specificity (0.746) to periodontal disease. The binary logistic regression analyses indicated that older subjects (OR = 2.5), or those who did not frequently visit a dentist (OR = 4.1), brushed their teeth only once a day (OR = 2.5), did not use dental floss (OR = 2.9), were past smokers (OR = 3.1), current smokers (OR = 4.1), or had positive BANA test results (OR = 12.0) were more likely to have periodontal disease.
Salivary biomarkers for predicting the progression of chronic periodontitis
Archives of Oral Biology
Salivary ALT level and the P. gingivalis ratio may be potential indicators for the progression of periodontitis. Such a salivary test could be a useful diagnostic tool for predicting periodontal disease progression.
Feasibility study of a salivary occult blood test to correlate with periodontal measures as indicators of periodontal inflammation in a population of pregnant women
Journal of Oral Science
Pearson correlation coefficient with the percent of sites with BOP was statistically significant (0.301, value 0.0469), and with BOP as the sum of sites with bleeding on probing was 0.280, value 0.0647.
A new screening method for periodontitis: an alternative to the community periodontal index
BMC Oral Health
The sensitivity and specificity for hemoglobin levels were, respectively, 0.722 and 0.711, for lactate dehydrogenase levels. Combining these two tests, when samples tested positive for both hemoglobin and lactate dehydrogenase, the positive predictive value was 91.7%.
